    "Magic Potion! My menopausal skin crisis happened just as this product was launched. My skin was suddenly reacting to products I had used for months/years. It was red, dry, flaky and thick. I took a chance and bought the Ectoin Hydro-Barrier Serum to see if it would help. It did an amazing job of calming my skin."

Reviews Summary
Customers say this serum provides deep hydration and makes skin feel plump and smooth. Many reviews mention improved texture and reduced dryness with regular use. The lightweight formula absorbs quickly, though some note it can pill under makeup. While most find it gentle and soothing for sensitive skin, a few report it wasn't hydrating enough for their needs. Common feedback highlights its effectiveness when used on damp skin and as part of a layered routine. Reviews are particularly positive about its smoothing effects and ability to enhance skin's natural moisture.

    Not sure

    Love most of the Inkey products I have tried so far but this one is bit of an odd one, yes it does what it say on the tin in terms of calming skin down, but leaves sticky film on my face. Kind of like after using a mask. Rolling off and cannot be used on my face under make up, only nighttime, and I need extra moisturiser or gives mw odd tense skin sensation after application, like it's not absorbing but creating a film on you skin

    Great serum for skin barrier

    I've had problems with damaged skin barrier for years. Most products I've used either did nothing or clogged my pores. I was looking for a light product I could use in the morning and that would still be effective, because a lot of products with light texture don't do much for my skin. I've seen a big difference with this product and it really helps with the skin barrier.
